ON THIS PAGE: You will learn about the different treatments doctors use for people with this type of tumor. Use the menu to see other pages.
This section tells you the treatments that are the standard of care for this type of tumor. “Standard of care” means the best treatments known. When making treatment plan decisions, patients are encouraged to consider clinical trials as an option. A clinical trial is a research study that tests a new approach to treatment. Doctors want to learn whether the new treatment is safe, effective, and possibly better than the standard treatment. Clinical trials can test a new drug, a new combination of standard treatments, or new doses of standard drugs or other treatments. Your doctor can help you consider all your treatment options. To learn more about clinical trials, see the About Clinical Trials and Latest Research sections.
In cancer care, different types of doctors often work together to create a patient’s overall treatment plan that combines different types of treatments. This is called a multidisciplinary team. Cancer care teams include a variety of other health care professionals, such as physician assistants, oncology nurses, social workers, pharmacists, counselors, dietitians, and others.
The most common treatment options for a parathyroid tumor are surgery, radiation therapy, and treatment of hypercalcemia. Chemotherapy may also be recommended. Treatment will include efforts to both eliminate the tumor and control the amount of calcium in the patient’s bloodstream.
Descriptions of these common treatment options are listed below. Treatment options and recommendations depend on several factors, including the type and stage of the tumor, possible side effects, and the patient’s preferences and overall health. Your care plan may also include treatment for symptoms and side effects, an important part of your care. Take time to learn about all of your treatment options and be sure to ask questions about things that are unclear. Talk with your doctor about the goals of each treatment and what you can expect while receiving the treatment. Learn more about making treatment decisions.
As explained in the Introduction, a parathyroid tumor can cause high levels of calcium in the blood. Having too much calcium in the blood, which is a condition called hypercalcemia, can cause serious problems. It may need immediate treatment.
There are a number of medications used to reduce calcium levels in the blood, including bisphosphonates (Aredia, Bonefos, Loron), calcitonin (multiple brand names), gallium nitrate (Ganite), plicamycin (Mithramycin), or zoledronic acid (Zometa). Most of these drugs are only used for short periods until treatment to remove the tumor can be started.
Surgery is the removal of the tumor and some surrounding healthy tissue during an operation. Surgery is the main treatment for a parathyroid tumor, whether the tumor is benign or cancerous. A surgical oncologist is a doctor who specializes in treating a tumor using surgery. Because parathyroid cancer is so rare and it cannot be cured if it has recurred, surgery with a surgical oncologist who has extensive expertise in thyroid and parathyroid surgery is strongly encouraged whenever parathyroid cancer is suspected.
It is difficult to know before surgery whether a parathyroid tumor is benign or malignant. Parathyroid cancer is the likely diagnosis whenever a patient has profound hypercalcemia, defined as a calcium level greater than 13 mg/dL, or a large parathyroid tumor, defined as larger than 3 centimeters. If this is the case, the parathyroid gland and surrounding structures should be removed. Those surrounding structures should include the same side of the thyroid gland, fatty tissue and lymph nodes surrounding the parathyroid tumor, and the overlying muscle of the center of the neck, called the sternothyroid muscle. The typical surgery for a benign parathyroid tumor is not the same as the surgery for a parathyroid cancer. The doctor may also recommend radiation therapy after surgery to the affected area of the neck (see below).
Surgery for a benign parathyroid tumor is called a parathyroidectomy. Talk with your surgeon about whether minimally invasive surgery for a benign tumor in a single gland is an option for you.
If a surgeon finds the tumor is benign during surgery, it is common to check the patient’s level of PTH in the blood during the operation. If necessary, the surgeon will then put back 1 of the normal parathyroid glands that had been removed earlier in the operation. However, if the tumor is cancerous, the gland should not be put back to avoid any chance of putting cancer cells back into the body.
Before surgery, talk with your surgeon about what to expect, how long recovery will take, and the possible short- and long-term side effects. Learn more about the basics of cancer surgery.
Radiation therapy is the use of high-energy x-rays or other particles to destroy cancer cells. A doctor who specializes in giving radiation therapy to treat cancer is called a radiation oncologist. A radiation therapy regimen, which is your treatment plan, usually consists of a specific number of treatments given over a set period of time. This may also be called a schedule.
Occasionally, radiation therapy may be recommended after surgery for parathyroid cancer. Radiation therapy may help reduce the risk of parathyroid cancer recurring in the neck, but it is difficult to evaluate whether this treatment is beneficial because this type of cancer is so rare.
Side effects from radiation therapy may include fatigue, mild skin reactions, upset stomach, and loose bowel movements. Talk with your doctor about how side effects can be relieved or managed during treatment. Most side effects go away soon after treatment has finished. Learn more about the basics of radiation therapy.
Chemotherapy is the use of drugs to destroy cancer cells, usually by ending the cancer cells’ ability to grow and divide. Chemotherapy is given by a medical oncologist, a doctor who specializes in treating cancer with medication.
Systemic chemotherapy gets into the bloodstream to reach cancer cells throughout the body. Common ways to give chemotherapy include an intravenous (IV) tube placed into a vein using a needle or in a pill or capsule that is swallowed.
A chemotherapy regimen, or schedule, usually consists of a specific number of cycles given over a set period of time. A patient may receive 1 drug at a time or combinations of different drugs given at the same time.
Chemotherapy rarely works at treating metastatic or recurrent parathyroid cancer. More clinical trials are needed.
The side effects of chemotherapy depend on the individual and the dose used, but they can include fatigue, risk of infection, nausea and vomiting, hair loss, loss of appetite, and diarrhea. These side effects usually go away after treatment is finished.
Learn more about the basics of chemotherapy and preparing for treatment. The medications used to treat tumors are continually being evaluated. Talking with your doctor is often the best way to learn about the medications prescribed for you, their purpose, and their potential side effects or interactions with other medications. Learn more about your prescriptions by using searchable drug databases.
Getting care for symptoms and side effects
Parathyroid cancer and its treatment often cause side effects, such as hypercalcemia, described above. In addition to treatments intended to slow, stop, or eliminate the cancer, an important part of cancer care is relieving a person’s symptoms and side effects. This approach is called palliative or supportive care, and it includes supporting the patient with his or her physical, emotional, and social needs.
Palliative care is any treatment that focuses on reducing symptoms, improving quality of life, and supporting patients and their families. Any person, regardless of age or type and stage of cancer, may receive palliative care. It works best when palliative care is started as early as needed in the cancer treatment process. People often receive treatment for the cancer at the same time that they receive treatment to ease side effects. In fact, patients who receive both at the same time often have less severe symptoms, better quality of life, and report they are more satisfied with treatment.
Palliative treatments vary widely and often include medication, nutritional changes, relaxation techniques, emotional support, and other therapies. You may also receive palliative treatments similar to those meant to eliminate the cancer, such as chemotherapy, surgery, or radiation therapy. Talk with your doctor about the goals of each treatment in the treatment plan.
Before treatment begins, talk with your health care team about the possible side effects of your specific treatment plan and palliative care options. During and after treatment, be sure to tell your doctor or another health care team member if you are experiencing a problem so it can be addressed as quickly as possible. Learn more about palliative care.
Metastatic parathyroid cancer
If cancer spreads to another part in the body from where it started, doctors call it metastatic cancer. If this happens, it is a good idea to talk with doctors who have experience in treating it. Doctors can have different opinions about the best standard treatment plan. Also, clinical trials might be an option. Learn more about getting a second opinion before starting treatment, so you are comfortable with your chosen treatment plan.
Your treatment plan may include a combination of surgery, chemotherapy, and radiation therapy. Palliative care will also be important to help relieve symptoms and side effects.
For many patients, a diagnosis of metastatic cancer can be very stressful and, at times, difficult to bear. Patients and their families are encouraged to talk about the way they are feeling with doctors, nurses, social workers, or other members of the health care team. It may also be helpful to talk with other patients, including through a support group.
Remission and the chance of recurrence
A remission is when cancer cannot be detected in the body and there are no symptoms. This may also be called having “no evidence of disease” or NED.
A remission may be temporary or permanent. This uncertainty causes many people to worry that the cancer will come back. While many remissions are permanent, it’s important to talk with your doctor about the possibility of the tumor returning. Understanding your risk of recurrence and the treatment options may help you feel more prepared if it does return. Learn more about coping with the fear of recurrence.
If the tumor does return after the original treatment, it is called a recurrent tumor. It may come back in the same place, meaning it is a local recurrence, or nearby, which is a regional recurrence. If it comes back in another place, it is a distant recurrence.
The first sign of recurrence after treatment may be high blood calcium levels. Therefore, you may have regular tests to watch for PTH and calcium level changes, as well as ultrasounds of the neck (see Diagnosis).
If there is a recurrence, a new cycle of testing will begin again to learn as much as possible about the tumor. After this testing is done, you and your doctor will talk about your treatment options. Often the treatment plan will include the treatments described above, such as surgery, chemotherapy, and radiation therapy, but they may be used in a different combination or given at a different pace. Your doctor may suggest clinical trials that are studying new ways to treat this type of recurrent tumor. Whichever treatment plan you choose, palliative care will be important for relieving symptoms and side effects.
People with recurrent disease often experience emotions such as disbelief or fear. Patients are encouraged to talk with their health care team about these feelings and ask about support services to help them cope. Learn more about dealing with recurrence.
If treatment doesn’t work
Recovery from cancer is not always possible. If the cancer cannot be cured or controlled, the disease may be called advanced or terminal.
This diagnosis is stressful, and for many people, advanced cancer is difficult to discuss. However, it is important to have open and honest conversations with your doctor and health care team to express your feelings, preferences, and concerns. The health care team is there to help, and many team members have special skills, experience, and knowledge to support patients and their families. Making sure a person is physically comfortable and free from pain is extremely important.
Patients who have advanced cancer and who are expected to live less than 6 months may want to consider a type of palliative care called hospice care. Hospice care is designed to provide the best possible quality of life for people who are near the end of life. You and your family are encouraged to talk with the health care team about hospice care options, which include hospice care at home, a special hospice center, or other health care locations. Nursing care and special equipment can make staying at home a workable option for many families. Learn more about advanced cancer care planning.
After the death of a loved one, many people need support to help them cope with the loss. Learn more about grief and loss.
